Switched to ikiwiki
So, I finally tried it, and I liked it, and I switched :)
My problem with nanoc was that while I love ruby as a language, managing the site with it was a real nightmare, with all the libraries breaking compatibility every second week. I don't post too often (just look at the archive), but every single time that I wanted to do it the damn thing was broken, hence the change.
OTOH the wiki scheme fits my needs better, and hopefully it will be a more stable setup since it's already included in Debian.
